Product details
Overview
TLV9161SIDBVR from Texas Instruments is a single-channel, rail-to-rail input/output precision operational amplifier optimized for high-accuracy signal conditioning in industrial and test equipment. It delivers ±210 µV offset voltage, 11 MHz gain-bandwidth product, 33 V/µs slew rate, 6.8 nV/√Hz input voltage noise at 1 kHz, and operates from 2.7 V to 16 V supply. It is used in high-side current sensing, multiplexed data acquisition, and professional microphone front-ends.
For engineers reviewing the TLV9161SIDBVR datasheet, TLV9161SIDBVR pinout, TLV9161SIDBVR application, or TLV9161SIDBVR equivalent, key selection criteria include low drift (±0.25 µV/°C), MUX-friendly inputs enabling comparator-mode operation, robust EMIRR performance, and guaranteed operation across –40°C to +125°C.
Technical Context
The TLV9161SIDBVR employs a precision CMOS input stage with rail-to-rail common-mode range extending to both supply rails, supporting true MUX-friendly operation and open-loop comparator use. Its architecture integrates high-speed compensation for unity-gain stability and delivers 110 dB common-mode rejection at DC with 11 MHz bandwidth and 33 V/µs slew rate.
It features low-input bias current (±10 pA), ultra-low noise (4.2 nV/√Hz broadband), and high short-circuit output current (±73 mA). The device maintains stable performance across its full 2.7 V–16 V supply range and specified temperature range (–40°C to +125°C), making it suitable for demanding industrial signal chains.

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA391IDBVR | Lower noise (4.7 nV/√Hz), lower offset (±125 µV), but narrower supply range (1.7 V–5.5 V) and reduced CMRR (100 dB) | Better suited for low-voltage, ultra-low-noise portable instrumentation; not rated for 12 V or 16 V rails | Select when operating ≤5.5 V and prioritizing noise over supply flexibility |
| AD8605ARTZ-R7 | Higher offset drift (±1.5 µV/°C), higher quiescent current (1 mA), but superior offset (±65 µV) and wider temp range (–40°C to +125°C) | Preferred for ultra-low-offset DC-critical applications like strain gauge bridges; less optimal for high-speed or low-drift AC-coupled designs | Select when absolute offset dominates over drift and noise in sub-100 kHz applications |
Compared with OPA391IDBVR and AD8605ARTZ-R7, the TLV9161SIDBVR uniquely balances 11 MHz bandwidth, ±0.25 µV/°C drift, 16 V operation, and MUX-friendly inputs-making it optimal for industrial multiplexed sensing and high-voltage precision signal chains where supply headroom and thermal stability are critical.

FAQ
What is the operating temperature range for TLV9161SIDBVR?
The TLV9161SIDBVR is specified for continuous operation from –40°C to +125°C ambient temperature. This extended range supports deployment in harsh industrial environments such as factory automation controllers, motor drives, and outdoor test equipment where thermal cycling and elevated ambient temperatures are common. All key parameters-including offset voltage, CMRR, and gain-bandwidth-are guaranteed across this full range.
Does TLV9161SIDBVR support rail-to-rail input and output operation?
Yes, TLV9161SIDBVR supports true rail-to-rail input and output operation. Its input common-mode voltage range extends from V– to V+, and its output can swing within 6 mV of either rail under no-load conditions. This capability enables full utilization of supply voltage headroom in single-supply systems and simplifies level-shifting in multi-stage analog signal chains without external bias networks.
Can TLV9161SIDBVR be used as a comparator?
Yes, TLV9161SIDBVR can be used open-loop as a comparator due to its MUX-friendly inputs-its differential inputs operate reliably up to the supply rails, and it exhibits no phase reversal or latch-up under overdrive. However, it lacks built-in hysteresis or dedicated comparator output logic, so external hysteresis or post-amplification may be required for noise-immune digital decision-making in production systems.
What is the typical quiescent current of TLV9161SIDBVR?
The typical quiescent current of TLV9161SIDBVR is 2.48 mA per amplifier at 25°C and 2.7 V–16 V supply. At –40°C to +125°C, it remains tightly bounded between 2.48 mA and 2.98 mA. This low, stable current draw supports thermal management in densely packed PCBs and enables reliable operation in power-sensitive industrial modules without compromising precision or speed.
Is TLV9161SIDBVR pin-compatible with other devices in the TLV916x family?
No, TLV9161SIDBVR is not pin-compatible with dual or quad variants (e.g., TLV9162 or TLV9164) due to differing channel counts and pinouts. However, among single-channel versions, TLV9161SIDBVR shares the same 5-pin SOT-23 (DBV) footprint and pin configuration as TLV9161DBVR-but differs in shutdown functionality (TLV9161SIDBVR has no shutdown pin; TLV9161SDBVR does). Always verify pin mapping against the specific variant's datasheet before layout reuse.
